python pandas Initializing from file failed 错误

在学习 pandas与numpy中遇到下列代码

import seaborn as sns
planets = sns.load_dataset('planets')
planets.shape

结果报错：

OSError: Initializing from file failed

网上搜索发现是:

pandas.read_csv()中参数问题，一检查发现，报错中的确有提到这个函数

G:\Anaconda3\lib\site-packages\seaborn\utils.py in load_dataset(name, cache, data_home, **kws)
    425         full_path = cache_path
    426 
--> 427     df = pd.read_csv(full_path, **kws)
    428     if df.iloc[-1].isnull().all():
    429         df = df.iloc[:-1]

于是添加参数到之前输入的函数中去

import seaborn as sns
planets = sns.load_dataset('planets',*{'encoding':'utf8','engine':'python'})
planets.shape

完美解决：

python pandas Initializing from file failed 错误
